Multicolor electrophotographic print engine

a multi-color, electrophotographic technology, applied in the direction of electrographic process equipment, optics, instruments, etc., can solve the problems of inability to print colors that contain vivid reds or greens, the size of such a cylinder is prohibitively large and expensive, and the electrophotographic printers have other limitations, so as to improve the color gamut, enhance gloss, and provide abrasion resistance

Embodiment Construction

[0024]FIG. 1 shows a electrophotographic (EP) engine (100) or printer, often referred to as a tandem print engine including EP modules (110A, 110B, 110C, 110D, and 110E), wherein each contains a single primary imaging member (115A, 115B, 115C, 115D, and 115E) and a single development station (117A, 117B, 117C, 117D, and 117E) to print on receiver 111. In addition, a sixth EP module (112) is shown containing development stations 113A and 113B which form a multi-development station 114. The EP printer is shown having dimensions of A×B which are around in one example, 52×718 mm or less.

[0025]FIG. 2 shows a slightly larger printer where B is expanded to accommodate the second multi-development engine. This new engine is designed so that the multi-development stations are able to be incorporated into a smaller engine using larger imaging members than are normally used. Development stations 110A though 110E would typically contain toner (T) that is typically used in most color prints. For...

Abstract

A method and system for printing image documents using a variety of toners where some toners using a multi-development station having two or more development stations. These toners are co-printed prior to fixing, on the receiver by the multi-development station.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application relates to commonly assigned, copending PCT Application Serial No. ______ (Docket No. 95996DPS), filed ______, entitled: “MULTICOLOR ELECTROPHOTOGRAPHIC PRINT ENGINE” and U.S. application Ser. No. ______ (Docket No. 96004DPS), filed ______, entitled: “MULTIPASS ELECTROPHOTOGRAPHIC PRINT ENGINE” each hereby incorporated by reference.FIELD OF INVENTION[0002]This invention relates to an electrophotographic print engine. More specifically, this invention describes an apparatus capable of printing images using a multi development station.BACKGROUND OF THE INVENTION[0003]In order to produce a print using electrophotographic means, a primary imaging member, also referred to as a photoreceptor or a photoconductor, is first uniformly charged. An electrostatic latent image is then formed by image-wise exposing the charged using known methods such as an optical exposure system, an LED array, or a laser scanner. The primary imaging m...
